they change the ratio of fuel delivered. Without a proper RR tune up, they can cause a bit of damage.
Running lean - burns the valve seats - preignition
Running Rich - bore wash

but your sayin that if you get it setup on a RR there good as n e thing ? and safe ??

without other major mods you'll probably feel no difference in the engine.
